A2P 10DLC Campaign Vetting Delays: Twilio cannot approve 10DLC Campaigns ourselves, and must rely on third parties who control our connections to carriers to sign off. These external processes are creating several week delays for our customers. We continue to escalate these issues and are working to reduce delays wherever possible. Further details will be shared in the Campaign Vetting Changes article as they become available.

Local Caller ID (CLI) international compatibility

Local Caller ID (CLI) refers to the Caller-ID when making in-country calls. For example, when you call from a French number to a French mobile number, the local Caller ID is the number that the recipient of the call sees as the caller.

Twilio only can guarantee local Caller ID (CLI) for calls made to:

  • United States, Canada and Caribbean Islands with +1 prefix
  • All European Countries

We can not guarantee local Caller ID in other countries around the world.
